Temperature

With the onset of December, the average high-temperature stands at a still tropical 31.2°C (88.2°F), closely aligned with November's 33.3°C (91.9°F). An average low-temperature of 21.2°C (70.2°F) is expected during December.

Heat index

December's mean heat index is estimated at a sweltering 35°C (95°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.
Understand that the heat index values take into account shaded locations and mild winds. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Humidity

In December, the average relative humidity is 60%.

Persist with safeguards and heed sun safety doctrines. Keeping sunburn at bay is of prime importance. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. On sunny days, it's ideal to wear sunglasses that filter out UVA and UVB rays.
